The comparisons are made separately at vertical loads of 200, 400, 600 and 800 kg. Using the Interpolation model as a benchmark the results plotted for the ‘Magic Formula’ and Fiala models are compared in Figures 5.72 to 5.79. The plots show that the more detailed ‘Magic Formula’ will produce a better match than the simpler Fiala model when examining the variation in lateral force with slip angle. Comparing the ‘Magic Formula’ with the
